What Owners Say
Eagle crankshafts generate mixed opinions among engine builders and enthusiasts. While some appreciate the affordability and availability of these 4340 forged cranks for 8-cylinder builds, others note concerns about quality consistency and reports of cracking issues that have affected the brand's reputation. Experienced builders point out that Eagle cranks often require more balancing work and additional heavy metal compared to premium alternatives like Callies, which can offset the initial cost savings of $200-300. The general consensus places Eagle cranks in a similar material quality tier as Scat, offering a budget-conscious option for street and moderate performance applications, though serious builders often recommend investing in higher-tier options for demanding builds.
